体化する方法により行なわれている。Rod-shaped rubber connectors formed with parallel conductive paths perpendicular to the longitudinal direction have come to be widely used in a state where they are clamped and/or crimped between objects to be connected. Conventionally, to manufacture this kind of rod-shaped rubber connector, parallel conductive paths made of conductive resin or conductive rubber material were formed on the surface of a flexible insulating film or sheet, and this film or sheet was separated. After laminating the uncured raw rubber sheet and curing it into one piece, it is cut into a rod-like body by cutting it in a plane substantially perpendicular to the parallel conductive path, or it is made into a parallel printing paper made of conductive material. A so-called transfer sheet with a pattern applied thereto is placed in a cavity having a rectangular cross section of a compression mold, and then a rod-shaped body made of preformed semi-cured rubber is placed in the cavity and compression molded.
This is carried out by taking the sheet out of the mold and finally peeling off the transfer sheet from the rod-shaped body to transfer and integrate the conductive parallel pattern onto the surface of the rod-shaped body.

かつた。However, although both of the above two methods are suitable for manufacturing rod-shaped connectors having a rectangular cross section or a cross section similar to this, they have a major drawback in that they cannot be applied to manufacturing rod-shaped connectors having other irregular cross sections. With the former method, it is difficult to obtain high dimensional accuracy because compressive deformation occurs in the rubber sheet when cutting it, while with the latter method, a rod-shaped body with a rectangular cross section that will be the core material of the connector must be preformed. However, none of these methods were fully satisfactory as a method for producing this type of rod-shaped connector on an industrial scale.

いという問題があつた。Therefore, in order to solve the drawbacks of the above-mentioned conventional methods, the present inventors first developed a compression molding mold having at least one groove-like cavity extending linearly on the molding surface, using a conductive resin or rubber material on the surface. A composite sheet-like body in which a film or sheet with parallel conductive paths formed thereon and an uncured rubber sheet are laminated is placed in a state in which the parallel conductive paths are substantially orthogonal to the groove-like cavity, and heated in the mold. We have proposed a method for manufacturing a connector (Japanese Patent Application No. 119813/1989) characterized in that the pressure is applied to both sides of the cavity to the extent that the composite sheet member is substantially pressed, and this method improves dimensional accuracy. This method makes it possible to simultaneously obtain a large number of rod-like connectors with a relatively simple cross-section other than a rectangular cross-section. When manufacturing a composite sheet, it is not possible to uniformly and densely fill every corner of the cavity with the composite sheet material, so it is necessary to ensure that the molding condition of the corners of the irregular cross section, especially the acute corners, is sufficiently satisfactory. There was a problem with kimono.

It is characterized in that it is charged so as to be perpendicular to the peripheries of the cavities and the convex portions, and when the mold is heated and pressurized, the composite sheet-like material is pressurized to the extent that the periphery of the cavity is substantially pressed. KaedeAccording to this, by protruding the convex portion of one mold into the cavity of the other mold, the composite sheet-like material can be uniformly and densely filled to every corner of the cavity, which is advantageous. It is possible to easily obtain a connector that is molded evenly over the entire cross section. The method of the present invention will be explained in detail below.

Conductive ink or paint is coated on one side of a flexible insulating film or sheet made of woven or nonwoven fabric impregnated with polyester resin, allyl phthalate resin, triazine resin, etc., using screen printing or offset printing.

本発明に従つて圧縮成形用金型を用いて成形される。Alternatively, it is also possible to form parallel conductive paths by laminating and integrating metal foil on one side of the film or sheet, by forming a parallel conductive path by etching after providing a metal vapor deposition layer, or by vapor deposition. Methods include forming parallel conductive paths directly on a film or sheet, or forming parallel conductive paths by bonding and integrating separately prepared linear or ribbon-like bodies made of conductive material onto the film or sheet. You can also get it. The sheet having parallel conductive paths according to the present invention can also be obtained by laminating and integrating a sheet made of an insulating synthetic resin or synthetic rubber sheet and the conductive matrix to form a block-like body, and then slicing this thinly in the lamination direction. It can also be obtained by The above-mentioned flexible sheet having parallel conductive paths on its surface is then laminated with an uncured rubber sheet in the presence of an appropriate adhesive and coupling, if necessary, to form a composite sheet. This uncured rubber sheet is made of known synthetic rubber materials such as silicone rubber, nitrile rubber, and neoprene rubber, in addition to non-sulfur-based crosslinking agents or curing agents that do not bleed residue, reinforcing fillers, and plasticizers. , an uncured rubber compound containing known additives such as colorants, stabilizers, heat resistance improvers, blowing agents, thermal conductivity improvers, coupling agents, etc., separated in a conventional manner. . In this lamination, the parallel conductive paths may be placed inside or outside the overlapping surfaces, and if they are placed inside, the parallel conductive paths may be partially embedded in the insulating rubber layer. Re,
Parallel conductive paths are exposed on the working surface of the rod-shaped connector, while when the parallel conductive paths are placed on the outside, the parallel conductive paths are slightly protruded from the surface of the connector after molding. This structure is selected depending on the conductive material, the material of the insulating sheet, the connector shape, the manner of use, etc.
In addition, when manufacturing a connector using a composite sheet in which parallel conductive paths are printed on the surface of a flexible insulating film or sheet and the parallel conductive paths are laminated on the inside, the above Although the film or sheet is peeled off after the elastic connector is formed, if the film or sheet is peeled off immediately before use of the connector, it can serve to protect the conductive paths. The composite sheet-like body previously prepared as described above is then molded using a compression mold according to the present invention.

る。The compression molding mold used for carrying out the present invention is:
It is made up of at least two molds, namely an upper mold and a lower mold, with one mold having a cavity and the other mold having a protrusion that projects into the cavity when both molds are fitted together. The convex portions function to uniformly and densely fill every corner of the cavity with the uncured elastomer of the composite sheet-like material charged in the cavity in a fluid state. be.

硬化される。The above-mentioned mold is provided with a protrusion or an acute angle portion that acts like a cutting edge along the periphery of the cavity and, if necessary, the periphery of the convex portion. The composite sheet is loaded into the compression mold in such a way that the parallel conductive paths of the composite sheet are approximately orthogonal to the circumferential edge of the cavity and the circumferential edge of the convex portion. After loading the composite sheet into a compression molding mold, the mold is heated to a predetermined temperature and a predetermined pressing force is applied to it, causing the two uncured rubber layers of the composite sheet to enter the cavity. is filled and hardened.

剥し取ることができる。At this time, the flexible sheet having parallel conductive paths is deformed along the inner surface of the mold cavity according to the shape of the mold cavity, and the uncured rubber layer located below the convexity is extruded into the cavity interior space of the convexity. Since the uncured rubber flows in a circular motion, the pressure distribution of the uncured rubber flowing inside the cavity becomes more uniform, and as a result, the tension acting on the sheet-like material inside the cavity, especially the film or sheet that holds the parallel conductive paths, is small. Therefore, there is no possibility that the parallel conductive path will break. If the upper and lower molds are separated after compression molding is completed as described above, a hardened rod-shaped rubber connector can be obtained from each cavity. If pressure is applied to the extent that the composite sheet is not completely sheared and separated by the protrusions or acute angles on the periphery of each cavity, but is substantially pushed through with only one skin remaining, the elastomer inside each cavity can be removed. The chip connectors can be peeled off from the mold cavity all at once in a sheet-like state.
